DRYING-ROOM TUMIBLEB.

Application fled Septemherlli, 1926. Serial No. 135,556.

This invention has for its object a drying room tumbler or a device for drying clothes which is particularly simple in construction,

economical in operation and highly efliclent o and durable in-use.

' The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference 15 had to the accompanying drawing in which like characters designate corresponding parts in all the views.

b Figure 1 is an end elevation of this tumler.

Figure 2 is an enlarged vertical cross sec tional view taken centrally on Figure 1.

Figure 3 is a central, vertical, longitudinal, sectional view taken at a right angle to Figure 2.

Figure 4 is a perspective clothes support.

Figure 5 is a fragmentary detail view illustrating the joint between each outer edge of the support and the inner face of the casing.

This drying room tumbler comprises generally, a horizontal casing, an oscillating clothes support mounted in the casing to rock about the axis of the casing, the support being formed with passages through which the air passesd'uring the oscillating of the support, means for drying the air in the casing during the movement of the air by the support or during the movement of the support and means for oscillating the clothes support. 1

view of the 1 designates the casing which may be of any suitable f0rm,.size and construction, it being a cylinder lying or supported on one side and having a door 2 at its top. This doorris suitably mounted to slide, into open position in order that clothes may be placed in and removed from the casing. Also, after the drying operation is started, this .door is opened more or less to permit a circulation of air and the escape ofmoist air.

3 designates the clothes support which is in the nature of a pivoted latform mounted on a shaft 4 arranged coaxially with the cylinder or casing 1 and extending atone end to the outside thereof.

The clothes support is here shown as provided with a perforate portion 5 which provides the passages for the air, this perforate portion being formed by panels of wire mesh. The wire mesh is held between upper and lower plates 6, 7 and these plates are formed along their middle portions with cylindrical-corrugations 8 which form a hub on the shaft 4. The plates are further reinforced by straps 9. The upper and lower plates 6, 7 are secured together in any suitable manner and at their outer margins are shaped to form a channel 10, see Figure 5. In the channel is provided means for wiping on the inner walls of the casing and providing a sliding sealed joint. This sliding sealed joint is provided by strips of a packing1 material 11 slidable in the channel 10 an being constantly pressed into engagement with the inner walls of the casing by springs 12.

The means for drying the air during a movement of the air by the support extends in the casing in a radial direction and is located between the extreme positions A and B-assumed by the support when at the extreme ends of its movement. This means 1s here shown as a plurality of pipes 13 for a heating medium as steam, these pipes being located in a chamber 1 1 having perforations therethrough, the chamber is triangular in form and extends radially into the casing 1 with the apex thereof located beneath the shaft 4, Sealing means 15, similar to that formed by the channel '10, pack ing 11 and spring 12, are located at the apex of the chamber 14 to coact with the hub 8 of the clothes support. Also, a baflie plate 16 depends from the apex of the chamber 14 to near the base of the chamber so that the air must pass in contact with a maximum number of heated pipes 13.

The shaft 4 is" oscillated in any suitable manner and as here shown is provided with a crank arm 17 at one end which is connect ed by a connecting rod 18 to a crank arm 19 mounted on a shaft 20, which shaft is.

actuated from any prime mover as an elec. tric motor 21. The crank 17 is longer than the crank 19 so that a rotation of the crank 19 oscillates the crank '17.

In operation, the clothes C are thrown into the casing 1 on the Support. During the oscillating of the support, they roll from one end thereof to the other across the axis of the support and during the movement of the support, the air is circulated by the support which acts as a piston due to the fact that the wire screen first on one side and then'on the other, is closed against the passageof air by the clothesthereon so that the movement of this side of the support with the passages so closed, acts as a blade to force the air through the heating chamber 13 where the moisture is removed therefrom, and also acts to create a suction above the blade. The suction acts to draw air through or from the heating chamber and through the opposite half of the supportfrom which the clothes have tumbled and into the upper portion of the easing into the path of the clothes during the next movement of the support.

' This drying room tumbler is not only particularly simple, but is very eflicient and rapid in operation and can be built at a small cost.

What I' claim is: Y 1. A drying room tumbler comprising a horizontal cylindrical casing, an oscillatlng clothes support mounted in the casing concentric with the axis of the casing and ex-- tending diametrically of the casing, the support having a perforate portion providing passages for air, means for oscillating the support about its axis, and means for drying the air in the casing durin the circulation thereof by the movement 0 the support.

2. A drying room tumbler comprisin a horizontal cylindrical casing, an oscillating support mounted in the casing to rock about the axis of the casing, the support extending diametrically of the; casing and having means wiping on the ihner faces of the walls of the casing to form a sliding sealed joint, a compartment extending into the easing into the space located between the extreme positions of the support, the compartment aving means for, heating and drying air and openings for receiving the air circulated by the support and means for rocking the support during the oscillating thereof.

3. A dryin room tumbler comprising a horizontal cyl indrical casing, an oscillatlng clothes support mounted in thecasing to rock about the axis of the-casing, the support extendingidiametrically of the casing and having a perforate portiomproviding passages for air, an air drying and heating means-located in'the chamber-between the 'extreme positions assumed by the support and means for actuating the "support 4. A drying room tumbler comprising a horizontal cylindrical casing,'an oscillating extreme positions assumed by the support and means for actuating the support 5. A-drying room tumbler comprising a horizontal cylindrical casing, an oscillating clothes support mounted in the casing to rock about the axis of the casing, the support extending diametrically of the casing and having a perforate portion providing passages for air, the su port also having means at its margin for orming a sealed sliding joint between the support and the inner face of the casing and an air drying and heating means located in the casing between the extreme positions assumed by the support, said means having a part coacting with the susport at the axis thereoffor forming a sli ing sealed joint between said means and the support, all whereby the air circulated by the movement of the support with the clothes thereon passes through the heating and drying means, and means for actuating the support.
